This is the Cast Iron Bracket that bolts to the Engine Block, then the Air Conditioner Compressor bolts to it.

There are two versions of Air Conditioner Compressors, a 3 bolt and a 4 bolt.
The correct one can be chosen by checking the date of manufacture found on build decal on the driver side door jamb. Or by looking at the Air Conditioner Compressor and figuring out if it has 3 or 4 mounting bolt holes.

This is the 4 bolt Later version
